The new Supergirl film faces a narrative hurdle common to many adaptations of powerful comic book heroes: how to create meaningful stakes when the protagonist is nearly invincible. Kara Zor-El, unlike her more optimistic cousin Clark Kent, is portrayed as a cynical and surly character. However, she possesses the same formidable array of superpowers, including flight, super-strength, laser vision, and invulnerability.

This inherent strength, while beneficial for saving the day, presents a significant challenge for filmmakers aiming to craft an engaging story that tests the hero. Past Superman films have grappled with this issue, and according to critics, Supergirl struggles to overcome it, with the hero's own powers ironically becoming the film's Kryptonite. The movie reportedly scales back the titular hero's abilities, preventing her from reaching her full potential to allow for narrative tension.

Creating a compelling narrative for characters with immense power requires careful consideration of their vulnerabilities, motivations, and the specific threats they face. The challenge is to balance the spectacle of superpowers with the human element and the dramatic tension necessary for storytelling. When a character can effortlessly overcome most obstacles, writers must find creative ways to introduce conflict, whether through moral dilemmas, personal relationships, or antagonists who possess unique abilities or cunning strategies that can challenge the hero.
